[IA64] Fix build breakage
In commit 0ac0c0d0f837c499afd02a802f9cf52d3027fa3b
cpusets: randomize node rotor used in cpuset_mem_spread_node()
Jack Steiner fixed a problem with too many small tasks being
assigned to node 0. Copy his code to ia64 to avoid build error.
arch/ia64/kernel/smpboot.c:641: error: ‘cpu_to_node_map’ undeclared (first use in this function)
In commit 3bccd996276b108c138e8176793a26ecef54d573
numa: ia64: use generic percpu var numa_node_id() implementation
Lee Schermerhorn added some set_numa_node() calls - but these
only work on CONFIG_NUMA=y configurations. Surround the calls
with #ifdef CONFIG_NUMA
